I’ve seen a poorly optimized and/or coded site crush a very powerful dedicated server under a very small number of visitors and I’ve also seen a shared hosting account handle millions of visitors per month without breaking a sweat.
Sometimes I do wish it were as simple as saying, ‘If you have X resources then you can handle Y visitors.’ The issue is that it really depends on your site(s) and how intensive they are.
Just like I can’t say ‘Every person in the USA can run 1 miles in 10 minutes,’ because some are able to do so due to being in decent shape and others absolutely cannot even come close to a 10 minute mile. While it’s probably possible for most without some major disability to get to that point – just like most sites can be optimized to perform better – that doesn’t mean I can simply say that everyone can do it now.

I’m planning to rent it as shared hosting. How many sites the server can host and how many concurrent visitors the site can handle using CDN?
Anywhere from 1 to 10,000 – probably closer to ~100. If you host nothing but static sites you could probably do 10,000 if you’re hosting Magento installations probably closer to 5. It’s all relative to the content of each site and/or account.
